Economical 32-bit MCU handles motor control apps

The Z32F0642 is a new Cortex-M0 32-bit MCU billed as ideal for motor control applications. Developed by
Zilog, a wholly-owned subsidiary of IXYS Corp., the MCU features 64KB of Flash memory, 4KB of SRAM, and operating frequencies up to 40 MHz. It offers a three-phase pulse width modulation (PWM) generator unit suitable for inverter motor drive systems. A built-in three-phase PWM generator can control one inverter motor. One 12-bit high-speed analog-to-digital converter (ADC) with 12-channel analog multiplexed inputs is included to gather feedback from the motor. There are multiple powerful external serial interfaces (one-channel SPI, one-channel I2C, and two-channel UARTs) to communicate with on-board sensors and devices.

The Z32F0642 can operate from a supply voltage ranging from 2.2 to 5.5 V. Other features include free-run timer, watchdog timer, on-chip RC-oscillator, power-on reset, GPIOs, hardware divider, and brownout detector. This new MCU is available in a 32-pin (10-channel ADC) or 48-pin (12-channel ADC) low-profile quad flat package (LQFP).
